(jump to 1:32 for the randomization)
Answers can be randomized on the Multiple Choice element, Image Answer element, and the Dropdown element.
When this option is activated, answers are presented to your participant in a random order, although the order of the questions themselves is not changed.
Note: Answers are only randomized in the participant view and in the design preview. In the editor itself and in the analytics, it will always be presented in the configured order.
